Internet routing is designed to be fault-tolerant.
What implications does that have for the Internet's performance during a natural disaster?
A natural disaster can never bring down the Internet because there will always be enough routes available.
The Internet can keep routing messages as long as enough routes stay available, but it could be brought down entirely.
The Internet can be switched over to use the emergency network routes, which cannot be brought down.
If a natural disaster happens, the Internet will activate more routes in order to send emergency messages faster.

Bett sends an instant message to her friend Mielle over the internet. Their computers use the TCP/IP protocols to communicate.
What's the best description of how Bett's computer sends the message?

Bett's computer splits the message into packets and sends it to her home router. That router looks up the best routing path in a routing table, records the path in the packet, and sends it to the next router in the path. The packet follows the path until it gets to the final destination.
